Automotive side sill reinforcement structure

Abstract

A reinforcement member ( 32 ) of an automotive side sill includes a V-shaped cross-sectional portion ( 46 ) formed by bending the reinforcement member so as to follow a lower surface ( 31 b ) of an upper portion ( 31 a ) of an outer panel ( 31 ), joining an upper attaching portion ( 42 ) functioning as a resulting bent portion to the upper portion ( 31 a ) of the outer panel ( 31 ) and bending a distal end of the upper attaching portion ( 42 ) downwardly.

1. An automotive side sill, comprising: an outer member and an inner member, each having a substantially U-shaped cross section; and
 a reinforcement member disposed in a longitudinal direction, and respectively jointed to said outer member and inner member at respective inner and outer side surfaces of said reinforcement member at upper and lower ends of said reinforcement member, said reinforcement member creating a closed cross-sectional construction between said reinforcement member and said inner member said reinforcement member including a substantially V-shaped sectional portion comprising:  
 a first leg that follows a lower surface of an upper portion of said outer member; and  
 a second leg connected to said first leg, the second leg defining an acute angle with said first leg.
